Early chapter books

I haven't posted on early readers because many of these books are very short and can be easily perused by a responsible adult while at the library.  However, this is a short list that we found to be fun and enjoyable.  None of them contain objectionable language like swearing or potty language.  All have color pictures on nearly every page.  Some may contain content that may be upsetting for very sensitive readers but if your child can watch Sesame Street without a problem they shouldn't be an issue.  I am talking about things like a character getting mildly sick and having to stay home for the day, or something getting lost, only to get found again, or a character telling a lie but getting found out and it being dealt with gently but appropriately, or a thunderstorm that doesn't do any real damage.

Poppleton series, Cynthia Rylant
Mr. Putter and Tabby series, Cynthia Rylant
Annie and Snowball series, Cynthia Rylant--may be more appropriate for girls, but there is plenty of Henry and Mudge in them too, for the boys.
Henry and Mudge series, Cynthia Rylant
Frog and Toad, Arnold Lobel
Houndsley and Catina series, James Howe

Fly Guy series, Tedd Arnold  --just keep in mind that some people don't like flies and swat at them, or they can get swallowed by old ladies.
Danny and the Dinosaur series, Syd Hoff  --does contain reference to millions of years (for those old Earth Creationists out there), main character is a boy (actually I'm not sure if these are chapter books per se, but they are about the same length as the other books in this list)

Golly Sisters series, Betsy Byars -- Golly is just a name, not a cuss word in this book;  best for girls
Cowgirl Kate series, Erica Silverman--I thought my son would think these were boring, but he relates most to the horse!
Boris and Morris series, Bernard Wiseman--DD thought these were funny, but not every small kid is going to understand some of the puns.
Amelia Bedelia series, Peggy Parrish--DD thought these were funny too, but I'm not sure she really understood the figures of speech.   These are definitely girl books.
